Expected strategy of Key alliances

The 21st century is expected to see a number of significant changes in the international political landscape, including the evolution of existing alliances and the formation of new ones.

Some of the key highlights include:

• NATO: The North Atlantic Treaty Organisation (NATO) is expected to continue to be an important alliance in the 21st century. This is particularly true as concerns about the security and stability of Europe continue to grow, and as new challenges such as cyber warfare and terrorism emerge. NATO is also expected to continue its role in providing collective defence and promoting stability in the Euro-Atlantic area.
  
• QUAD: The Quadrilateral Security Dialogue (QUAD) is a strategic dialogue between the United States, Japan, Australia, and India. The QUAD is expected to play an increasingly important role in the 21st century, as it aims to address common security challenges and promote cooperation among its member states. The QUAD is also expected to be an important counterbalance to the growing influence of China in the region.
  
• BRICS: The BRICS (Brazil, Russia, India, China, and South Africa) is expected to continue to be an important alliance in the 21st century. This is particularly true as these countries continue to experience significant economic growth and political influence, and as they seek to promote cooperation and coordination on global issues such as trade, climate change, and security.
  
• G20: The Group of Twenty (G20) is expected to continue to be an important forum for international cooperation in the 21st century. The G20 brings together leaders from the world’s largest economies to discuss and coordinate on global economic issues, and it is expected to play an increasingly important role in addressing issues such as global trade, climate change, and financial stability.
  
• SCO: The Shanghai Cooperation Organisation (SCO) is an intergovernmental organisation which is primarily focused on security, economic and diplomatic cooperation among its member countries. The SCO is expected to play an increasingly important role in the 21st century as it aims to address common security challenges and promote cooperation among its member states.

• ASEAN: The Association of Southeast Asian Nations (ASEAN) is expected to continue to be an important alliance in the 21st century. ASEAN is a regional intergovernmental organisation comprising ten Southeast Asian countries that aims to promote cooperation and coordination on issues such as security, trade, and economic development.
  
• The Arab League: The Arab League is an intergovernmental organisation of Arab states in and around North Africa, the Horn of Africa, and Arabia. It is expected to play an increasingly important role in the 21st century as it aims to address common security challenges and promote cooperation among its member states in the Middle East and North Africa.
  
• The African Union: The African Union (AU) is an intergovernmental organisation that aims to promote cooperation and coordination among African countries. The AU is expected to play an increasingly important role in the 21st century as it aims to address common security challenges, promote economic development, and improve governance on the continent. The AU is also expected to play a larger role in addressing issues such as peace and security, humanitarian affairs, and the promotion of democratic values.
  
• The Lima Group: The Lima Group is a regional organisation comprising mostly American countries, and it was created in 2017 to address the political crisis in Venezuela. It is expected to play an increasingly important role in the 21st century as it aims to address common security challenges and promote cooperation among its member states in Latin America.
  
• The European Union (EU): The European Union is a political and economic union of 27 member states that are located primarily in Europe. The EU is expected to continue to play an important role in the 21st century as it aims to promotion cooperation and coordination among its member states on issues such as trade, economic development, and security.

It’s important to note that these are just a few examples of the alliances that are expected to be important in the 21st century. Other alliances and organisations may also emerge as the international political landscape continues to evolve. It’s also important to note that alliances and organisations can evolve and change over time, and the role and importance of any particular alliance may also change depending on the global political and economic situation.
